To find: Solve system of equation by elimination.
This is a dependent system that has infinite solutions.
Given information:
The given system of equation is:
Concept used: Elimination
Calculation:
Rewrite the equation (1)
Now equation (2) and (3) represents the system of equation
If we add equation (2) and (3) it gives:
The condition for consistency is
Check the condition
Hence the lines coincide and the pair of equations is dependent and consistent. these lines coincide with each other, then there exist infinitely many solutions since a line consists of infinite points.
